4040H wiring diagram needed

[Treadnmud]

I am looking for a complete wiring diagram. Tractor is an open station model. Having starting issues and need to get alternator wiring cleaned up so it works properly and does not drain battery.

John Deere's TM1181 technical manual has the info you want.

There is a copy you can download at Archive.org

Here is a link to it if it works.

On subject of starting problems have you checked to be sure starter relay mounted in front of firewall above starter is receiving a good ground connection? I'll also advise for you to clean tighten all battery cable connections paying special attention to where ground connections to frame are located.

Did you try the pdf? It is large so it will take some time.

I cleaned up all the battery cable connections, both ends, and used a blade type terminal cleaner to get clean, smooth insides for the round post terminals. Load tested battery, ok. Installed a new solenoid on the starter because the contacts had high resistance. Cranked perfectly after so that solved that problem but now I am not getting a signal to that solenoid anymore. Trying to get a diagram so I can troubleshoot. So, no, I have not checked the solenoid on the firewall.

The pdf is grayed out showing a lock symbol saying it is not available for download.

It is not that way on my computer. Try clicking on parent directory and see if it is different there.

Also non operating neutral start switch located on RH side of trans case can cause a non start condition.
